re: Inside the Waistband (IWB) Holsters -- Features to Avoid

No, you're not "missing" anything. But it is a Fobus holster in the video.

Yeager was semi-famous for doing this in his classes for years. He'd ask if anyone had a Fobus, then he'd proceed to do exactly what you saw in the video. It was a visual teaching aid that apparently made quite an impression on students (Never saw this personally in the classes I took).

Then he'd give the student a new holster (brands that were handed out varied over the years).
